Title: Switching apparatus with an upper buck transistor
Inventor: HUBER ANDREAS
IPC: H05B44/00
Filed: 2006-11-22
Abstract: The invention provides a cost-effective driver circuit for an LED background lighting unit (BLU). For this purpose, a buck circuit with an upper transistor (T1) is provided. The buck transistor (1) is driven via two further transistors (Q1, Q2). The first transistor (Q1) is connected with its reference electrode to the positive terminal of a DC voltage source, with its working electrode to the control electrode of the buck transistor (T1) and with its control electrode, via a capacitor (C3), to a signal contact, which can be driven externally. The second transistor (Q2) is connected with its reference electrode to ground, with its working electrode to the control electrode of the buck transistor (T1) and with its control electrode to a signal contact (K5), which can be driven externally. The buck transistor (T1) can be switched on via a corresponding gate signal at the terminal (K5) for the purpose of operating the light-emitting diodes (D5 to D10). Advantageously, cost-effective standard transistors (Q1, Q2) for operating voltages below 100 V can therefore be used for the switching controller.

Title: Process for the preparation of polyesters containing 1,4-cyclohexanedimethanol
Inventor: MARTIN DANIEL LEE
IPC: C08G63/183
Filed: 2007-04-18
Abstract: Disclosed is a process for the preparation of high molecular weight polyesters by reacting one or more dicarboxylic acids directly with 1,4-cyclohexanedimethanol and, optionally, one or more diols. The process uses an overall diol to dicarboxylic acid molar ratio of about 0.97 to about 1.2 and an incremental addition of either the diacid or diol components. The process provides a shorter total reaction time and, thus, lessens the thermal degradation of polyester which may result in high color and reduced molecular weight. ® KIPO & WIPO 2009

Title: Method and system for securing wireless communications
Inventor: GUCCIONE LOUIS J
IPC: G06F21/44
Filed: 2007-04-18
Abstract: A wireless transmit/receive unit (WTRU) and a Node B, respectively, perform joint randomness not shared by others (JRNSO) measurement to generate JRNSO bits based on a channel estimate between the WTRU and the Node B. The WTRU and the Node B then perform a reconciliation procedure to generate a common JRNSO bits. The Node B sends the common JRNSO bits to a serving network. The WTRU and the SN secure a session key (such as an integrity key, a cipher key and an anonymity key), using the common JRNSO bits. The JRNSO measurements are performed on an on-going basis, and the session key is updated using a new set of common JRNSO bits. The JRNSO bits may be expanded by using a pseudorandom number generator (PNG) or a windowing technique. A handover may be intentionally induced to increase the JRNSO bits generation rate.
